ORG: none TITLE: Thermal stresses in a cylindrical shell with an annular-cross-section core SOURCE: IVUZ. Aviatsionnaya tekhnika, no. 4, 1965P 90-96 TOPIC TAGS: thermal stress, cylindrical shell ABSTRACT: Sometimes it is advantageous to use in aircraft design a sandwich-like construction.1%onsisting only of a skin with a core of annular cross section,e.9-1 a sandwich plate or shell without. an Inner face I.ayer. During high-speed flights, thermal stresses will be generated due to the temperature variation over the thickness of the shell. These thermal.. stresses are determined in a long cylindrical shell with a tubu- l.jr core, assuming that the temperature in the skin is constant, and varies linearly in radial direction in the core, but the variation is not too strong, so that the modulus of elasticity can be tonsidered constant. The hypothesis of straight normals is applied to the skin, and the general stress-strain relationships of the theory of elasticity are used in the treatment of the core. Expressions are derived for deter- mining the stresses, strains, and displacements in the core produced by the differ- ence of temperatures on its inner and outer surfaces, and by the radial pressure exerted by the skin on the core. The skin is treated as a thin cylindrical shell Card 1/2 UDC: 539.3+621.438 ACC N91- W6003187 acted upon by the radial pressure developed by the core, and expressions are also derived for stresses, strains, and displacements. The resulting distribution of thermal stresses in the shell is obtained by summation of two component states of stresses obtained from the above-mentioned expressions by introducing into them boun& ary conditions associated with temperatures at the inner and outer shell surfaces. A numerical example illustrating thermal-stress analysis in a shell of the discussed type is given. Orig. art. has: 1 figure and 28 formulas. IVKI SUB.

TYKACHINSKIlf 0 A , z Steklo i K -6-T27-3-5 (1949).--Both soda and sulfate charges were used in studying the effect of F2, F2 + B203 and F2 + MhO + A5203 + B203 on the rate of glassmelting at temperatures from 13500 to 14500. With or without the use of accelerators, the process was accelerated with rising temperature. For axj,,,,ordinary charge (no acoelerators) a rise from 13500 to 4500 cut the time about one-fourth. The 1% F a addition of 2 t*1350' and at 14500 reduced the time one half; the addition of F2 + B203 produced similar results. Simultaneous use of high temperatures and accelerators caused a further reduction in processing time. Some reduction in the activity of the accelerators at high temperatures was caused by volatilization. Fluorine also facilitated the fining, reducing the volume of residual gases. The accelerator F2 + MnO + B203 + AS203 was tested only with a soda charfe at 13500 and 14000; the total time reduction, compared with the ordinary charge, was over one-third.

ElLimination of silica crust at the surface of the glass melt was effected by incor- poration of 1% Cao as calcium sulfate. A series of glasses have been developed in which the sum of alkaline-earth oxides is constant, and the proportions of MgO and CaO approximate those of dolomite. As a result of studies of crystallization and viscosity a series of glass compositiens are recommended. One of them (glass 110 13) con- tains [in % by weight): Sioa 61.91-AI203 18.5, CaO 15.4, MgO 4.2, F1 4 (in excess of 100); it is characterized by the following proper- ties: coefficient of linear expansion 43-45 - 10-7, thermal conduc- tiv-:Lty coefficient (at 70-3500). 0.75-0.77 kcal/m degree hour, the=al capacity (at 25-3600) o.472-0.208 kcal/kg degree, Young modulus 7,350- 7,500 kg/~n2, specific gmvity 2.6 g/=3, flexural strength 620 kd=2, microhardness 935-975 kg/=2. The investigated glasses show high electric insulating properties.

The experimental curves show I that at any temperature of exposure in the investigation range, the density and refractive Index asymptotica*Ily approached the same limiting value. The coef-~ ficient of light transmittance approached zero asymptotically. Deformation curves Card 1/2 ACCESSION NR: AT11019301 for glass under static compression at different temperatures are given, and the correlation between the character of the deformation and the changes In physical constants is plotted at a temperature of thermal treatment of 710C. On plotting the same curves at other temperatures, In the same time interval, It could be seen that the deformation curves of Isothermal static compression reveal changes In the physical properties of the initial glass during Its crystallization. Com- pression tests on samples of Initial glass of the Li2O-AI2O3-SIO2 system using other mineralizers showed that the deformation curves have an analogous slope.

It is shown that of the three ammonium salts that were investigated the greatest acceleration of the vitrifica- tion process is produced by (NHO00j, added in amounts from 3 to 5% depending on the compos tion of the mix.

Acceleration of Smelting and of the Production of Plate Glass (Uskoreniye varki i vyrabotki listovogo stakla). PERIODICALs Steklo i Keramika, 1958# Njr 2, pp. 1-4 (USSR) ABSTRACT: The increase of the production output of plate glass is intended, for the greater part, to be attained by an intensification of the production process. The main factors in this connection are the smelting temperature, suitable additions to the smelt, and the f ine granulation of the material of the layers. Fig. I shows the depend- ence of the time of smelting on temperature. Stepanenko found by analyzing the work of factory plants that an increase of tempera- ture from 1430 to 14900 increases the specific production output of glass by approximately 56%,,whioh is also confirmed by Litvakovskiy. At present Soviet plants are working with temperatures of from 1460 to 14700. Melting temperatures of from 1490 to 15000 are permissible with the present refractory equipment of furnaces. By the work Card 113 carried out at the Institute for the Utilization of Gas AN USSR Intensifio&tion of Production Processes. 72-2-1/20 Acceleration of Smelting and of the Production of Plate Glass it was shown that by using a combined fuel the heat transfer of the torch can be increased, which is also confirmed by the works by W.A. Zakharikov and A.I. Rozhanskiy. By works carried out by the Institute for Glass several chemical additions were determined by which the process of smelting was accelerated, among others the fluorides combined with boron-anhyaride, CaP21 amonium-sulfate, and others. The work "Proletariy" has been using annonium-sulfate with good success since November 1957, as shown by the papers by Engver, Katayeva and Orlova. The accelerating affect of the aaai- tions is conserved also at higher temperatures an may be seen from the illustmtion. The Soviet scientists Kitaygoroaskiy, Uyakhlov, and others as well as experiments carried out by the Institute for Glass showed that, by using a finely ground layer, the smelting pro- cess can be accelerated by 25 to 30%. The Institute for Glans, to- gether with VNIITIM, developed a combined scheme of grinding. The influence exercised by a finely ground layer upon the time taken by smelting at different temperatures may be seen from fig. 3. To- gether with the increase of the efficiency of smelting furnaces it card 213 is, however, necessary to increase also the efficiency of the Intensification of Production Processes.

For this purpose a glass mass with a content of 4% MSO 1 14,8% alkali oxides, and 1 6-1 8% A1203 ' as well as with an addition of 0,5-2,0% K20, instead of the corresponding quantity of N&20, is suited.

PERIODICAL Steklo i Keramika, 19,58, Tir 2, pp. 4-5 (USSR) ABSTRACTs The beat effect is attained by an addition, with respect to weight, of 3% ammonium-sulfate. The authors describe in detail what invest- igations they carried out ando occasionally, also refer to a previous work. The following conclusion is drawns Ammonium-sulfate forms chemical ocmpounds with the layer components as well as with the layer as a whole. The existence of (NH )2SOLL in the layer, thanks to its being melted at a temperature of 3%0, leads to the formation of a liquid intermediate layer, by which interaction amon 'g layer compo- nents is promoted. In the temperature range of 350-530 the ammonium- sulfate decomposes into the gaseous products NH SO and H20. The amonia acts mechanically upon the layer by u2n'g i~.

Comparison of the MZssbauer spectra of the initial glass and of glass subjected to heat treatment (I hr at 7500C) showed that (1) the spectrum of the initial glass is displaced by 0.06 mm/sec to the left relative to the heat-treated glassq whose spectrum coincides seLth that of crystallIne Sn02 (cassiterits)" (2) the Card 1/2 UDC; 54-161.62 f ACC NRt AP6023922 0 spectral lines in the initial glass are broader and the splitting is greater than in the heat-treated glass. The shift observed in the spectra is apparently due to the fact that in the initial glass the ionic character of the Sn-O bond is greater than in cassiterite. The large splitting of the spectrum indicates large gradients of electric fields acting on the tin rraclei in the vitreous state of the sample. The line broadening in the initial glass is due to the lack of rigorous ordering in the arrangement of the atoms closest to tin. The heat treatment causes ordering around the tin atoms to take placep i. o., cassiterite nucleation centers are formed, and this change in the short-range order is recorded in the change of the MOssbauer ef- fect. This is followed by a growth of cassiterito orystales, which become large enoug] to servo as centers for the growth of the main crystalline phase (spodumene). Further treatment causes a complete crystallization of the glass. Orig. art. has: 2 figures.

Byul. gos. n.-i. in-ta stekla, 1958, Nr 3 (100), pp 3 - 10 ABSTRACT: For the theoretical study of the rocesses of melti alkali-free glasses on the basis of the system SiO2-Al2O -Cav-MgO the ba-sic reactions taking place in the heating of the charge S~02+ A120 + CaCO3 + MgCO3 have been studied. This charge is the initial mixture hr obtaining glass containing 61.9% S102; 18.5% A1203; 15.4% CaO and 4.2% MgO. For a mor6 complete elucidation of the reactions taking place in the heating of a 4-component charge the processes in 2- and 3-component charges containing the same components were studied preliminarily. The quantitative ratio of the in- dividual components in all charges wa3 the same as in the 4-components charge. The processes taking place in the heating of the charge were studied by thermal, thermal-weight, microscopic and roentgen-phase analyses.

At 6000C a noticeable formation of C,11cl'Al aluminates, starts, mainly in the form 3CaC-A12O and 5CaO-3A12O3, Withm the range 450 - 1,OOOOC (the temperature range of Ca('03 dhsociation) the rate of Ca aluminate formation is higher than the rate of Ca silicate formation. Magnesium silicates are detected only at 7500C, An accelerated formation of aluminates and silicates is ob- served at 1,014 - 1,1500C. At 1,2000C the formation of a compound of the typp CaO,Mg0-.;LO, is detected roentgenographically. At 1,22'30C the formation of the liquid phase takes place corresponding to the melting of the eutect: Loslin the system forsterite-anorthite-quartz. The temperature of !,2680C corresponds to the beginning of the melting of the eutecticS of Ca and Mg silicates and aluminates.

This mechanism was observed in studying precipitation of carbides in Cr-W steelis, the results of which will be the subject of a separate paper. The investigated steels contained about 12.5% Zr, 0.5-0.69' C, 3 or. respectively, 70 5-5% W; the full composition is given in Table 1, on P 450. The steel was produced in a 10-1cg medium- frequency furnace with a magnesite lining and cast into ingots weighing 7 kg. For the tests, the ingots were forged into 16 nim dia rods which, prior to manufacture, were normalised from 900 OC and tempered for 2 hours at 700 OC and then cooled in air. Austenisation was effected at 1 300 -t+ 10 OC for 30 min. The isothermal treatment was effecTed in a thermostat and a "sleeve" furnace at Card 1/5 80268 Z/034/6o/ooo/Woo9/033 ~OZA/EJ3111oyed Austenite A New Mechanism of Isothermal Decom:Posi 1 0 650 4+ 3 OC. Long-run annealing of the products of isot"Rermal decomposition of austeni-te was effected in a 11sleeve" furnace after ea:-31ing the isothermally trans- formed specimens into quartz ampoules. After heat treatment, the surface layer was removed from all the specimens to a depth of 0.5 - 0.6 mm to eliminate the Influence of decarburisation. The electrolytic isolation of the carbides was effected by a method described in another paper. X-ray phase analysis of the isolated carbides was effected by -the Straumanis asymptotic method, using CoK al,2 radiation. The average exposure time was 2.5 hours (40 kV, 18 mA). For isolating the carbides the isothermally-treated specimens were subjected to metallo- graphic analysis. After removing a 0.5 mm thick layer from one of its faces, each specimen was ground on emery paper and polished and etched electrolytically in a bath consisting of glacial acet'Ic acid and perchloric acid (11:1). The electrolytic polishing and etching was effected Card 2/5 for 2 min at 0.5 A/cm 2 with intensive cooling of the 8o268 Z/034/6o/ooo/Woo9/033 UOK303alloyed Au,tenite A New Mechanism of Isothermal Decompositio 0 electroly-te by flowing water; most of the specimens had to be additionally etched with Vilella-Bain etching fluid. The exposures were made with magnifications of 20OX and 80OX. The results of X-ray study of a carbide phaseoof the decomposition products for a temperature of 650 C are entered in Table 2 for isothormal soaking periods of up to 5 000 hours. It was found that the two-phase (eutectoidal) decomposition of the solid solution is not connected with concentration changes in the main non-transformed body of the original phase. A typical example of such a decom- position is the formation of pearlite in Fe-C alloys. LII~K Du#,~ to the fact that its progress involves concentration changes in the main body of the non-transformed austenite, the non-steady state eutectoidal reaction is not a two- phase decomposition in the classical sense. Whilst the two-phase decomposition (pearlitic transformation) was intensively studied for carbon and low-alloy steels, the non-steady state reactions have been studied only in individual cases and their mechanism is almost unknown.

As a result of that, the eutectoidal transformation will stop after a certain time and the remaining austenite will decompose, bringing about formation of ferrite and precipitations of carbides in this formed ferrite. Thus4 the non-steady state eutectoidal transformation leads in the given case to qualitative changes of the mechanism of the decomposition, for instance, to an arresting of the eutectoidal trans- ~,K formation and to a-decomposition of the remaining austenite linked with the formation of ferrite and the precipitation of carbides in the ferrite, whereby the carbide particles increase primarily as a result of the diffusion of carbon from the non-transformed austenlte into the ~ferrite. The atechanism of the austenite decomposition, which is linked with ferrite formation and precipitation of carbides in Card 4/5 the formed ferrite, is described in the paper in considerable
